New powerheads, need advise

[RLHornbeck]

I am looking for some new powerheads. I want to upgrade to controllable pumps that will work with my new Apex system. I currently have 3 Koralia 4's but don't know which Tunze's I should get. I am looking at either 3-6055 nano's or 2-6105's.
Please help

Depends on what you are keeping. I would get the larger tunzes. On my 150G I will be using at least 2 vortech MP40Ws but probably go with 3. But I like a lot of random flow in my tank.

get 6105 but if the budget allow it you should get 6205 instead. bigger is better plus you can adjust the flow anyway. i just get 6201 and 6205 myself.I will remove some of the 6 koralia 4's

Yeah that's why I recommended the larger tunze's and not the nanos. Just letting him know the amount of flow I will have in my size tank for comparison.
